Influences Of Canopy Photosynthesis And Summer Rain Pulses On Root Dynamics And Soil Respiration In A Young Ponderosa Pine Forest
Misson, L., Gershenson, A., Tang, J., McKay, M., Cheng, W., Goldstein, A.
Our first objective was to link the seasonality of fine root dynamics with soil respiration in a ponderosa pine (Pinus ponderosa P. & C. Lawson) plantation located in the Sierra Nevada of California. The second objective was to examine how canopy photosynthesis influences fine root initiation, …

The Contribution Of Beneath-Snow Soil Respiration To Total Ecosystem Respiration In A High-Elevation, Subalpine Forest
Monson, R. K., Burns, S. P., Williams, M. W., Delany, A. C., Weintraub, M., Lipson, D. A.

The respiratory loss of CO2 from soil microbes beneath winter snow in forests from cold climates can significantly influence the annual carbon budget. We explored the magnitude of winter soil respiration using continuous measurements of beneath‐snow CO2 concentration within the footprint of a flux tower in a subalpine forest in …

An Eddy Covariance Mesonet To Measure The Effect Of Forest Age On Land-Atmosphere Exchange
Goulden, M. L., Winston, G. C., McMillan, A. M., Litvak, M. E., Read, E. L., Rocha, A. V., Rob Elliot, J.

We deployed a mesonet of year-round eddy covariance towers in boreal forest stands that last burned in ∼1850, ∼1930, 1964, 1981, 1989, 1998, and 2003 to understand how CO2 exchange and evapotranspiration change during secondary succession. We used MODIS imagery to establish that the tower sites were representative …

Model-Data Synthesis Of Diurnal And Seasonal CO2 Fluxes At Niwot Ridge, Colorado
Sacks, W. J., Schimel, D. S., Monson, R. K., Braswell, B. H.

Eddy covariance records hold great promise for understanding the processes controlling the net ecosystem exchange of CO2 (NEE). However, NEE is the small difference …

Winter Forest Soil Respiration Controlled By Climate And Microbial Community Composition
Monson, R. K., Lipson, D. L., Burns, S. P., Turnipseed, A. A., Delany, A. C., Williams, M. W., Schmidt, S. K.

Most terrestrial carbon sequestration at mid-latitudes in the Northern Hemisphere occurs in seasonal, montane forest ecosystems1. Winter respiratory carbon dioxide losses from these ecosystems are high, and over half of the carbon assimilated by photosynthesis in the summer can be lost the following winter2,3. The amount of winter …

Partitioning Of Evapotranspiration And Its Relation To Carbon Dioxide Exchange In A Chihuahuan Desert Shrubland
Scott, R. L., Huxman, T. E., Cable, W. L., Emmerich, W. E.

Key to evaluating the consequences of woody plant encroachment on water and carbon cycling in semiarid ecosystems is a mechanistic understanding of how biological and non-biological processes influence water loss to the atmosphere. To better understand how precipitation is partitioned into the components of evapotranspiration (bare-soil …

Influences Of Biomass Heat And Biochemical Energy Storages On The Land Surface Fluxes And Radiative Temperature
Gu, L., Meyers, T., Pallardy, S. G., Hanson, P. J., Yang, B., Heuer, M., Hosman, K. P., Liu, Q., Riggs, J. S., Sluss, D., Wullschleger, S. D.

The interest of this study was to develop an initial assessment on the potential importance of biomass heat and biochemical energy storages for land-atmosphere interactions, an issue that has been largely neglected so far. We conducted flux tower observations and model simulations at a temperate deciduous forest site in central Missouri …

Relationships Among Canopy Scale Energy Fluxes And Isoprene Flux Derived From Long-Term, Seasonal Eddy Covariance Measurements Over A Hardwood Forest
Pressley, S., Lamb, B., Westberg, H., Vogel, C.

The flux of isoprene, one of the more reactive biogenic volatile organic compounds, was measured using eddy covariance techniques on a continuous basis during the 2000–2002 growing seasons at a mixed hardwood forest in northern lower MI. Daytime fluxes of isoprene and both sensible (H) and latent heat flux (LE) were linearly …
